95 blazer fuel tank vent

Hey all,
Have been reading the forum often but am a new poster, lots of great info here for the backyard guy like myself. I recently replaced the fuel pump in my 95 blazer s10 4.3, and everything went well but I must have broke the nipple off the vent valve on the rear of the tank as I dropped the tank down (didn't know it was there) just wondering if this vent is a boneyard part, OE part, jobber part etc. or if I even have to connect the hose back up to it.

This may be helpful:

Thanks Blazee, wish I would of had that diagram before hand. I think I said in my post that it was the rear vent, it is actually the front one. Now that the tank is up and secure is there a trick to getting at this thing without dropping the tank again.
